Intercepting all touch events

Question

I have a UIViewController inside of a navigation based app. I'd like the view controller to receive all touch events from child objects, such as a tableview and navigation bar. Or, any other technique that is able to intercept all touch events.

Right now, the following never executes inside of the view controller:

 - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

I need to check a class level flag inside of the touch event, no matter where the touch came from (within any of the view's children).
